Key Capabilities
Render commercial tariffs live in your React UI
The `get_commercial_rates` tool pulls active commercial energy tariffs directly into your Vercel AI SDK frontend stream. Instead of making your users stare at a static loading wheel, you pipe the raw rate structures directly into your UI components as the data arrives from the API. This matters when you are building commercial solar calculators where speed determines whether a user stays on the page. You configure this by calling the `mcpClient.tools()` method and passing the output straight to your text generation engine. The agent identifies the commercial rates, and your application renders the breakdown instantly. There is no middleman and no custom backend polling code to write.
Resolve local rates with this geocoding MCP Server
The `get_rates_by_address` tool matches physical street addresses with their actual utility providers and active tariff schedules. Your UI takes a user's input, routes it through the Vercel AI SDK, and displays the exact residential or commercial rate options without requiring manual zip code lookups. Homeowners get instant feedback on their potential solar savings. This integration runs smoothly on Edge Functions, keeping your API latency low. You just pass the address string, and the system handles the geocoding and tariff lookup in one fast execution step.
Compare complex industrial rate structures in real-time
The `get_industrial_rates` tool retrieves heavy manufacturing tariffs, including complex demand charges and power factor penalties. Industrial energy modeling is notoriously messy, but streaming these rates directly into your Vercel AI SDK application lets you parse the data on the fly. Your users see the cost curves build out in real-time. To drill down further, you can chain the response to `get_rate_detail` for a granular look at seasonal variations. Your client handles the nested JSON data from the MCP Server and formats it into clean UI tables instantly.
Set up OpenEI MCP in Vercel AI SDK
Prerequisites
- Node.js 18+ and a TypeScript project
-
ai+@modelcontextprotocol/sdkpackages - Active Vinkius subscription with a valid endpoint token
- 1
Install dependencies
Run
npm install ai @modelcontextprotocol/sdkplus your preferred model provider (e.g.@ai-sdk/openai). - 2
Create the Streamable HTTP transport
Use
StreamableHTTPClientTransportwith your Vinkius endpoint URL. Replace[YOUR_TOKEN_HERE]with your token from cloud.vinkius.com. - 3
Discover and use tools
Call
mcpClient.tools()to auto-discover all OpenEI tools. Pass them directly togenerateText()orstreamText()— no manual schema definitions needed. - 4
Works with any model provider
Swap
openai("gpt-4o")for any AI SDK provider — Anthropic, Google, Mistral. The MCP tools work identically across all supported models.
import { experimental_createMCPClient as createMCPClient } from "ai";
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp";
import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";
const transport = new StreamableHTTPClientTransport(
new URL("https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp")
);
const mcpClient = await createMCPClient({ transport });
const tools = await mcpClient.tools();
const { text } = await generateText({
model: openai("gpt-4o"),
tools,
prompt: "List recent OpenEI transactions",
});
console.log(text);
await mcpClient.close();Independent Platform Disclaimer: Vinkius is an independent platform and is not affiliated with, endorsed by, sponsored by, verified by, or otherwise authorized by OpenEI.
